Need to turn string into variable

Hey all,
I have a bunch of checkboxes with different values in a form, when the form is submitted I am using the following to collect all the values:

Code:

chkCnt=request.form("pocertstring").count
i=1
if chkCnt > 0 then
do while i <=chkCnt
response.write request.form("pocertstring")(i) & ".pdf,"
i=i+1
loop
end if

I response write all the values and can see the results: 107541.pdf,111281.pdf,111398.pdf,
Great, but I need this in a variable so I can do something with it... by changing response.write to xxx=, I can only access the first value in the string.

Cancel this! This was way easier than I though. There is no need to count how many checkboxes were checked and then cycle through this amount. A simple cleanstring=Request.Form("pocertstring") is enough!
